IMPROVEMENT IN FLOAT-VALVES.

To ALL WHoM IT MAY eoNoERN: i

Be it known that I,-J. I-I.- GUILD, of Rupert, Bennington county, Vermont, have invented a new and improved Device for Regulating the Flow of Liquids; and I do hereby declare that the following is a full, clear, and exact" description thereof, which will enable othersskilled in the art to make and use the same, reference being `had to the accompanying drawings, forming part of this specification, in whichy v Figure 1 represents a sectional elevation of my apparatus. f

Figure 2 is a plan or top view of the same, partly in section. l

Similar letters of reference indicate corresponding parts.

This invention relates to a device whereby the ow of liquids into vessels ot any description may be regulated, so that the liquid may not rise above a certain mark.

The object of this invention is to-so arrange the apparatus that the valveswhich were heretofore used in similar devices, and which do generallyget out of order after having been usedv for some time, may be done away with. For this purpose I malte use of an India-rubber or other flexible tube, through which the liquid is fed intol the pan. As soon as the Alatter rises in the pan to a certain mark, it raises a iioat which is connected with a system of levers, whereby, as soon as the float is raised, the end of the flexible tube is compressed. The liquid is thus prevented from iiowing through the tube. As soon as the liquid in the pan diminishes the iioat will4 be lowered and. the tube opened again. The great. value of this tube is that it cannot get out of order. When, by wear or otherwise, that part where it islcompressed should be torn, the end of the tube can be cut o" and the tube moved forward and used again, and, it' totally destroyed, can be easily renewed. This invention is particularly applicable to the feeding of'vsap to the evaporating-pan, but may be used with equal advantage for other purposes. l

LA represents a cylindrical or other upright vessel, which is placed into the pan, into which the liquid is to bc filled. Ailoat, B, is arranged in the vessel A, made of any suitable material. The liquid is poured into the vessel A from any suitable receptacle-through an India-rubber or otherl lexible tube, C, the lend of which passes through a hole provided in the side of A, as shown. At the bottom of the vessclA are provided holes a a., through which the liquid flows into the pan or vessel in which A stands. To the'iioat B is secured a vertical rod,`Z, which is perforated, or otherwise so arranged that it may be'secured to an oscillating lever, c, which connects by a link, d, with lever e, as shown. The levcI` c is provided with a projectioinf, directly under the tube C, as shown, so that, as the iioat is raised, the lever c will depress that end ofe which is opposite to the end of the tube C, and thus the projection f will be raised and willpress against the tub'c C, against thecover of the vessel A, and compress the end of the tube, preventing any further flow of liquid 'through it. AS soon as' the float is lowered the tube Cwill again be opened.

I claim as new, and desire to secure by Letters Patent- The arrangcmentfin the perforated vessel A, of the loat B having the perforated or notched vertical rod b engaging with the pivoted oscillating lever c, connected by the'link d to the lever e, pivoted to the opposite sidp of the vessel in ysuch a manner that as the iloat B is velevated. by the water the projection f upon said lever e presses against the elastic pipe C, eifectually closing the same, substantially as described and for the purpose specified.
